SharePoint Online upload solutions programmatically

In SharePoint Online (365) I want to add solutions (.wsp) to the "Web Designer Galleries" (_catalogs/solutions/Forms/). I saw a post that said it is possible, but I haven't seen anything showing how. I would also like to activate these solutions as well, which that same post said is not possible. I am looking for any way to do this: JavaScript, REST, C#, PowerShell, whatever. I've been looking into this for a while and so far no dice. I'm really hoping I'm missing something here.
As the title states: I need to be able to do this programmatically. I need to be able to upload multiple solutions to the gallery at one time, or automated at least.

I had a similar question answered on sharepoint.stackexchange.com, see https://sharepoint.stackexchange.com/questions/90809/is-it-possible-to-activate-a-solution-using-client-code-in-sharepoint-online-201
You can use CSOM to upload a wsp file to a list, there are a few ways of doing this, depends on where you're wsp files are to be loaded from as well.

C# data scraping from websites

HI I am pretty new in C# sphere. Been in php and JavaScript since the beginning of this year. I want to scrap posts and comments from a blog. The site is http://www.somewhereinblog.net
What I want to do is
1. I want to log in using a software
2. Then download the html
3. Then use regular expressions, xpath whatever comes handy to separate the contents of posts and comments
I been searching all over. Understood very little. Though I am quite sure I need to use 'htmlagilitypack'. I dont know how to add a library to c# console or form application. Can someone give me some help? I badly need this. And I am not too into C# just a week. So would be grateful if there is some detailed information. Waiting eagerly.
Thanks in advance brothers.

Using Webclient you can login and download
Instead html-agility-pack I like CsQuery because lets you use jQuery syntax inside a string in C# code, so you can download to a string the html, and search and do things in it like with jQuery and HTML page.

Is it possible insert image to a code comment?

My question is probably an insane idea, however, it's very valuable when I write code for educational purpose.
Especially when the code is relevant to math and physics, images inserted in comment are more convenient and articulated.
Until now, I can't find a way succeed to insert a true image into comment, not C# nor python or any other common programming language or IDE.
Using tools that convert images to ASCII image is a workaround but less precise.
Any idea is appreciated

There is an example here that extend the Visual Studio 2010 editor: Image Insertion (but it's tied to Visual Studio, not a generic solution)

For Python you can use Google Colab.
Inside a text-block you can write something like:
![Alt text](https://someurl.com/image.png).
Example:
For C# you can try this plug-in:

Literate Programming tools work this way; you basically use TeX or something to write the code, then run a preprocessor which extracts the code snippets into an intermediate source file. http://en.wikipedia.org/wiki/Literate_programming

Using Sandcastle
Each SHFB project is it's own container for everything seen in the documentation project. When it's compiled, the (program project's") XML doc is pulled into SHFB to be put into the document.
If you want to show images in the top section of the class documentation, you must add the image to the SHFB project and refer to that image from the code comment. See Problem 2...
Problem 1:
"I can't get an image to show from a conceptual topic using the 'image' tag"
Make sure to use the proper XML markup similar to this:
<section>
<content>
<mediaLink>
<image xlink:href="MyMainImage"/>
</mediaLink>
</content>
</section>
Notice that the Href (above) doesn't have the file type associated,
this is because Sandcastle wants the ID instead.
Add the image to the project using the default media folder. Or, if you want you can create your own folder e.g Images.
Go to properties page of the image and set Build action to Image.
When you use an "image" tag, SHFB only uses the Image ID found in the properties page, seen in the HREF above.
Recompile the project and open up the CHM file and you will see the
image.
Problem 2:
"I cannot get an Image to show using Code commenting XML markup in the programming project".
In the summary section of the code comment, the markup can look like
this:
/// <summary>
/// <remarks><img src="\Images\MyImage.PNG"/></remarks>
/// </summary>
Note that the src attribute does contain the file type. It also must correctly identify the folder that your SHFB project has for that image.
After adding that image to the SHFB right click on it and change the "Build Action" property to Content
Happy coding and documenting!
Thanks goes to Eric W.

I politely disagree with #thekip reply. IDE is not just the editor, but a full set of tools, and thank God code editors has been evolving from the old times. That’s why:
Eons ago I was amazed with the AMOS developer tool for old AMIGA computers, that had the fold/unfold capability you can see now in many code editors, and during many years I was asking myself why Borland and Microsoft tools didn’t had it. It’s clear that information should not be always at the same level.
Code editors already had automatic text styling, to see different kind of reserved words or comments in different colors, allow auto indentation, and so.
Comments in code is an a topic in discussion out there, with some people defending that maintaining them under minims is the way to follow, arguing that they are usually not maintained by developers as they change code. People like me disagree with that, having in mind that comments are part of the code.
Not always all comments have the same importance, and 2020 tools should provide something better than UPERCASE and a bunch of dash separators ----------
Allow different font size, bold and italic in comments is the “must have” we will have again some eons later, and sometimes an image diagram in the same code could save you many time of search in the appropriate project documentation. Google Collab and other Jupyter tools seems to finally understood that.
All this should not replace project documentation through other tools, of course but, hey, do other people’s lives easier.
Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live.

#Simon Mourier reply for Visual Studio, rocks!

I found Jupyter Notebooks very valuable for teaching and used them with Python. They let you combine text, images and code.
Microsoft announced Jupyter Notebooks for .NET core and it is now in Preview in the .NET Interactive repo.

I had the same Idea and wanted to check if someone already shared it.
I just did it one way: Wordpad -> wrote code with an image between /* */ and saved as text document: images removed. just an empty comment zone remaining.
Of course, many interesting possibilities are missing from such an editor.
But all that is needed would be to allow a better suited one to include images.
It could greatly speed up the understanding of code if visual elements are involved.

Why don't use a free image hosting like http://imgur.com and insert image link to code comment?
Then the only problem for a student would be to copypaste link to browser from any IDE. Quite easy though.
Maybe some IDEs have the ability to "underline" links so that you can click it instead of copypasting.

Actually,you can always include the link of the image but cannot add an image to the comment of the code.

I think you're using the wrong tool for your problem. An IDE is a 'development' environment so it's not very important to have complete control over styling.
I would use something else (like LaTeX, see the comment) for you presentation.

TinyMCE like Richtext Editor for C# .NET?

Is there a good Rich Text WYSISYG editor for C# Winform applications? Something like an embeddable wordpad?

We are using TextControl, it supports RTF, PDF DOC, DOCX an it's very easy to integrate.

You could use something from one of the major winforms framework people. I use DevExpress http://www.devexpress.com/, mostly because that also gets me Coderush and Refactor Pro at the same price.
Other options are Telerik, Infragistics, etc.
These are not free, but you get fantastic customer support. Even my non-priority questions are answered in hours, sometimes even on weekends. By answered I mean some kind of code sample showing how to accomplish a task or work around a bug till it gets fixed.
You can also test drive them before buying to make sure you like their environments and solutions.

You can use ckeditor http://ckeditor.com/.
The download package includes samples with "asp" samples that can be "adapted" for asp.net and a lots of examples of different implementations.
In the practice this editors works like a multiline "textBox" area on the server side returting to you the html source of the control.

I would recommend http://freetextbox.com/. It's free and many browsers support it (Internet Explorer 6,7,8,9, Firefox 1,2,3, Google Chrome 1,2,3,4,5 etc.).
They also have a demo and documentation to play with on their website. The community is not really active. But there are topics about installation help and son on. By the time of writing this post the last message at the forum was placed 3 days ago.

Rich Text Editor on a web page

I am trying to add a rich text editor in my web page where users can write reviews and format what they have written...something similar to the editor in which we write our posts on this site...
can anyone point me to the right direction regarding this...any tutorial that would help me build such a component...
Also i want a free product....(Forgot to mention earlier...)

Something in the likes of TinyMCE or FCKeditor, perhaps.
They're quite complete, and customisable.

The editor used on Stack Overflow is the WMD Editor.
The current version used on the site has been updated by Jeff Attwood and other site users and you can read about it here and get a copy of the code for your own site.
I think you'd be better off using (and perhaps modifying) an existing component rather than writing your own from scratch.

I've been using the Telerik r.a.d Editor, and been very happy with it.

after much research here is what i did...
i needed a control that was free and easy to use..all the editors that i went through came with a licence so i decided to make my own control!!!!
well..i couldnt do that on my own so i used the help of a few sites....
javascript Rich Text Editors
http://aspalliance.com/1092_Rich_Text_Editor_Part_I
http://ws.aspalliance.com/1092_Rich_Text_Editor_Part_II and a few others too...
so the best option for me was to build my own control so that i could customize it according to my needs....
